CI crates.io license

Overview

This crate contains Starkom's quantum-resistant polynomial commitment scheme, a DEEP-FRI implementation.

It currently works on the BlueSky field only.

Three different hash backends are provided: one based on SHA-256 for fast verification on the EVM, one based on Poseidon, and one based on Poseidon2 for efficient recursion.

The SHA-256 hash backend is compatible with our EVM verifier.
